In the attached part (Figure 1) the intersection curve between the two surfaces at one point is disjoint doesn't lie on one of the surfaces (Figure 2). This isn't my first time encountering this. Is this a bug and is there anything to be done to fix this? Ultimately I am trying to use the surfaces to trim each other. This is the export of a larger part which I am hesitant to post here because of a NDA.
